The Infinity BassLink is an active subwoofer designed to enhance vehicle audio systems. It offers 200 Watts of RMS power and features a 10-inch driver. The system includes options for both line-level and speaker-level inputs, as well as an auto turn-on feature. Installation requires connecting power, ground, and audio signals, with specific configurations depending on the head unit’s output capabilities. The documentation details various connection scenarios and provides technical specifications for the device.
Understanding the BassLink System
The Infinity BassLink is categorized as an active subwoofer, meaning it incorporates its own internal amplifier. This simplifies installation compared to passive subwoofers, which require a separate amplifier. The system is designed to integrate with a variety of vehicle audio setups, offering flexibility in connection methods. The documentation emphasizes that while instructions provide a general guide, specific installation techniques will vary depending on the vehicle. Users lacking the necessary tools or experience are advised to seek professional installation.

Installation Procedures
The documentation outlines several connection scenarios for the BassLink, depending on the head unit’s available outputs. These include configurations for head units equipped with four line-level (RCA) outputs, two line-level (RCA) outputs and two speaker-level outputs, or four speaker-level outputs.
Regardless of the configuration, several core connections are required:
- Power Connection: A wire (at least #12AWG) must be connected between the vehicle’s positive battery terminal and the BassLink’s +BATT input.
- Ground Connection: A short GND wire must be connected from the BassLink to a bare metal surface of the vehicle.
- Audio Connections: Audio signals can be connected via either line-level (RCA) inputs or speaker-level inputs, depending on the head unit’s capabilities.
- Remote Turn-On (if applicable): If using only line-level inputs, the remote wire must be connected to the BassLink to enable the auto turn-on feature.
The documentation emphasizes the importance of proper grounding for optimal performance. The BassLink should be positioned so the controls face the trunk or cargo interior for easy adjustment. It also notes that the subwoofer’s placement within the vehicle will influence its sound characteristics due to the vehicle’s “transfer function” or “cabin gain.”
Auto Turn-On Feature
The BassLink incorporates an automatic turn-on feature. To enable this feature, the AUTO TURN-ON switch must be set to the “Д position. When enabled, the BassLink will automatically turn on when it detects a signal on the speaker wires (FRONT SERVO) or line-level inputs. The auto on/off time ranges from 1.5 to 5 minutes, depending on the last input signal level.
Safety Considerations
The documentation includes a warning regarding safe listening volumes. A volume exceeding 80 decibels can be harmful to hearing, and prolonged exposure to volumes above 120 decibels can cause direct damage. The risk of hearing damage is dependent on both the listening frequency and duration.
Remote Operation
The Infinity BassLink can be remotely operated using a wired remote control. This allows users to adjust the subwoofer settings without physically accessing the device.
Troubleshooting and Protection Features
The BassLink incorporates several protection circuits to prevent damage:
- Over/Under Voltage Protection: Protects against voltage fluctuations outside the range of 8.5 to 17.5 VDC.
- Temperature Protection: Protects against overheating, activating at 95°C.
- Short Circuit Protection: Protects against short circuits with a 0.1Ω resistance.
Manual Availability
The manual for the Infinity BassLink is available in English and can be accessed online.
Conclusion
The Infinity BassLink is an active subwoofer designed for vehicle audio enhancement. Its 200W RMS power, 10-inch driver, and flexible connectivity options make it a versatile addition to many audio systems. Proper installation, adhering to the guidelines provided in the documentation, is crucial for optimal performance and safety. The inclusion of features like auto turn-on and protection circuits contribute to ease of use and system reliability.
